4.2 Mounting on the wall
Mount the ComfoFond-L Q against a wall with a
minimum mass of 200 kg/m
frame (available as an optional extra) must be used
for other walls. This reduces contact noise as much
as possible.
Make sure to leave a minimum space of 110 cm in
front of the ComfoFond-L Q in view of the
necessary maintenance work.
ComfoFond-L Q TR
1. Align the wall mounting bracket supplied with the
unit to the wall, ensuring it is level and on a flat
surface. The suspension bracket should be fitted
at the same height as that of the ventilation unit
(see appendix: Wall-mounting pictures).
2. Place the ComfoFond-L Q in the wall mounting
bracket.
3. Rotate outdoor connecter bend (A) of the
ventilation unit and connect it to the supply air of
the ComfoFond-L Q.

C. Exhaust liquid connector
4. Fit the condensation drain to the underside of the
ComfoFond-L Q, as described in the chapter on
mounting the condensation drain.
5. Fit the fluid circuit (geothermal collector),
including the boiler safety group, to the exhaust
side (C) of the ComfoFond-L Q, as described in
the chapter on mounting the fluid circuit.
6. Connect the 2 electrical cords of the
ComfoFond-L Q to the ventilation unit, as
described in the chapter on mounting the
electrical connections.

3. Place the metal sleeve joint / 180-160 adapter (A) on
the niche pipe (outside air) of the ventilation unit.
Use the 180-160 adapter to connect the
ComfoFond-L Q to the ComfoAir Q 350 ST air
connection.
Use the metal sleeve joint to connect the
ComfoFond-L Q to the ComfoAir Q 450 or 600
air connection.
4. Use the EPP sleeve joint to connect both 90º
connection bends (B).
5. Place the connected 90º connection bends on
the metal sleeve joint / 180-160 adapter (A) of
the ventilation unit and the air exhaust of the
ComfoFond-L Q.

4.3 Connecting the condensation drain
Take account of the following factors (see also
Appendix: Condensation drain pictures)
when fitting the condensation drain:
The condensation must be drained off frost-free,
at a gradient, using an appropriate siphon;
Connect the condensation drain (air-tight) via a
pipe or a hose with a siphon (with a water seal of
at least 60mm) to the sanitary pipework;
Position the upper edge of the siphon at least 60
mm underneath the condensation drain of the
ComfoFond-L Q.
The condensation drains of the ComfoFond-L
Q and the ventilation unit must have a seperate
siphon. Do not connected them directly to the
same sifon.
